Paulownia tomentosa Paulownia tomentosa Princess tree Introduction All seven species of the genus Paulownia are reported to grow in almost all the provinces of China, except Inner Mongolia, northern Xinjiang, and Tibet. Members of this genus prefer to grow in well-drained soil with a pH of 6-8. Paulownia species are among the most popular cultivated trees in China[202].

It occurs below 1,700 m in Gansu, P. fargesii Franch. Henan, Hubei, Shaanxi, Shandong, Shanxi, and Sichuan[202]. Sichuan[202]. Taxonomy Family: Scrophulariales Natural Enemies of Paulownia Genus: Paulownia Sieb. et Zucc. Economic Importance At least ten species of fungi have been Similar to other members of the reported to infect members of the genus genus, P. tomentosa is cultivated for Paulownia. Eight fungal species can Description timber because of the texture of its Paulownia tomentosa is a woody tree live on P. tomentosa, four of which, wood, as well as its ability to tolerate that may reach 20 meters in height, with Ascochyta paulowniae, Gloeosporium harsh environments. It is also used a broad, umbelliform crown. The bark kawakamii, Mycosphaerella corylea medicinally [202]. is brownish gray. The branches have and Phyllactinia paulowniae appear numerous nodes and obvious lenticels; to be host specific.

The cordate leaves are organism, occurs on P. tomentosa is distinguished from Paulownia about 40 cm long, hairy on both surfaces, nationwide. There are 113 insects in tomentosa var. tomentosa by its round to with the underside especially so. The 39 families within 7 orders associated leaves have acute apices and entire or lobed margins; which distinguishes P. tomentosa from P. tomentosa var. tsinlingensis. The violet, bell-shape flowers of the pyramidal to narrowly conical thyrses bloom from April to May. Fruits are ovate capsules 3-4.5 cm long, coated with viscid hair when young. The capsules appear from August to September. Seeds, including wings, are 2.5-4 mm long [202]. Habitat and Distribution Paulownia tomentosa occurs naturally at elevations below 1,800 m in Henan, Hubei, Shaanxi, and probably northern Invasive Plants of Asian Origin Established in the US and Their Natural Enemies — 123 Paulownia tomentosa with Paulownia.
